Introduction: In spite of progress in dental material science, considering strength and bonding, PFM restorations still have 5 failure after 10 years. The main aim of this investigation was to choose a system with better bonding, more strength and esthetics, simpler technique and more durability. Materials & Methods : In this invivo investigation, twenty upper premolars were selected. The crowns were made in the usual manner and then a layer of porcelain was removed using stone from buccal cusp. In half of the samples both metal and porcelain were exposed and in the other half metal was not exposed. The crowns were cemented with Temp-Bond and then the fractured area was repaired intraorally with Vivadent system. The patients were recalled after 2 weeks, 1, 3,6 and 9 months to check durability and success rate of the restoration. Finally the data were analysed statistically. Results : We calculated the success rate of restoration to be 80 in porcelain-exposed group, 100 in porcelain-metal-exposed group and 90 totally. Conclusion : Intraoral porcelain repair, with the use of Vivadent system can be used instead of removing and remaking fractured crowns with satisfactory durability in long terms.
